Nanny

In The Sims 4, nannies or babysitters were not initially present in the base game, but were added in an update released on July 14, 2016. Nannies are random young adult, adult, or elder townies that will come take care of the baby/toddler/child when a Sim calls for the service, and can be male or female. Prior to this update, babies would automatically be sent to daycare when all other Sims had left the lot. Children can be left alone with babies, but cannot effectively meet a baby's needs. Now, when the last Sim leaves the lot the player will get a popup giving them the option to either hire a babysitter or send the baby/toddler to daycare, which is free but doesn't allow for toddler skill building. When nannies were first released in a patch, there was a glitch that would cause Sims introduced to the nanny to stop aging. This has been fixed in a later patch.

Nannies will cook meals and autonomously help children with homework in addition to basic baby/toddler care.
